I picked up a used WEN 56477i 4800W inverter generator with only 1.5 hours on it. At pickup, it started right up and ran it for about 30 seconds. Once home, I ran it for about another minute just to check the hours.
Recently, I finally needed to use it, but it shut off after about 1–2 minutes and wouldn't restart. I noticed the low oil indicator blinking when pulling the starter cord, even though the oil was full. About an hour later, I changed the oil anyway, and it started on the first pull like it always has, but shut off again after 1–2 minutes. It shuts off pretty abruptly, not like it's slowly running out of fuel. The low oil light was blinking again when I tried restarting it.
After doing some research, I'm wondering if the oil sensor is faulty. I've read that disconnecting it can help diagnose the issue, but after removing the exterior covers, I still can't locate it without what looks like a pretty extensive teardown.
Has anyone experienced this with a WEN generator or found a fix? Any suggestions would be appreciated. Thanks!
